That sweet whimpering sound that came from Sherlock’s lips was more than enough to tell Irene that she had most definitely done something right. She stopped rocking her hips over him and smiled down at him, basking in the way he closed his eyes and sighed, realising his mistake in showing her his weakness. “My, my, Mr Holmes,” she purred, her voice breathless as she spoke, her curls falling in her face as she straddled him. This was by no means their first fucking and she was certain this wasn’t going to be their last. However, this was the time that she had finally found his weakness. “What have we here?” She asked.
Sherlock groaned and his body arched, the same whimper falling from his lips as she tugged on his hair again. “Sensitive hair follicles,” he ground out honestly and she let out a sound of delight, something he enjoyed hearing. He bucked his hips up hard into her, making her gasp and she pulled his hair again.
"Behave, Mr Holmes. Or I’ll tie you up again," she warned, making him grin before he rolled them over, continuing to thrust into her, still trying to figure out her own weakness. He was so very close to cracking that particular case.
We all know it’s his hair (thanks to Benedict)! A little short but I hope you like it :)
